Well, the Xbox LIVE Marketplace has the first confirmed million dollar generating download in Activision's Call of Duty 2 Map packs.

Here is the map pack download details:

• Free Bonus Pack (2 Maps) - 334,000 downloads
• $5 Skirmish Pack - 105,000 downloads for a cool $368,000
• $10 Invasion Pack - 66,000 downloads for a cool $500,000

Here are some snippets from the analyst conference call:

"During the quarter our Call of Duty maps generated approximately $1 million in revenue, a critical first step in exploiting the online revenue potential and extending the shelf life of our games," said Kotick. "This holiday we'll look to further capitalize on the success of the franchise and its online capabilities."

With results like this we will certainly see future map packs and downloadable content from our friends at Activision (and in general from all publishers).  Positive side is that they will work on fresh content to liven up your old/tired multiplayers experiences.  Negative is that you probably won't see free downloads nearly as often...
